Researchers from the National Institute of Standards and Technology (NIST) and the National Institute of Genetic Resources (NHGRI) have succeeded in deciphering the sequence of the Y chromosome. It was considered the most difficult to solve. The results of the study were as follows: presented in the journal Nature.
The authors identified more than 62 million DNA pairs, as well as 41 new genes. A total of 106 protein-coding regions were found on the Y chromosome.
Most of the new genes are different versions of the same TSPY1 protein, which plays an important role in spermatogenesis. Maybe the number of TSPY1 has an effect on fertility, but scientists have yet to find conclusive signs of it.
According to the authors, this discovery will help develop new treatments for genetic diseases. The fact is that the male Y chromosome is associated with a number of hereditary diseases, such as Shereshevsky-Turner syndrome, Klinefelter syndrome and Jacobs syndrome.
“The Y chromosome is a unique source of information about human origin and evolution. It allows you to trace the pedigree of the male lineage from ancient times to modern populations and learn how they interacted with each other and the environment. The authors noted that the Y chromosome can also tell us how men’s lifespans vary, what factors affect their health, and what genetic traits make them unique.
